PRU is running at 200MHz and can read and write GPIO every 5ns. I think that's close to what the FPGA is capable of. Of course FPGA can then process these in parallel using independent hardware units, but still. > I was just trying to point out that ARM parts and boards are available > that more directly compete with the "traditional" Atom motherboards > currently popular here (including conventional PCI/PCIe expansion slots!). > As far as I can see, PCI/PCIe is the only differentiating factor, unless you imply that Atom-class means better quality, or better noise immunity etc. Low power should not be a big deal---after all, LinuxCNC is likely to drive electric motors rated in kiloWatts. ------------------------------------------------------------------------------ Introducing AppDynamics Lite, a free troubleshooting tool for Java/.NET Get 100% visibility into your production application - at no cost.
